Merge PDF files online

One file is easier to attach, upload and open than five. Merging is the fix whenever a form, a portal or a person wants everything in a single PDF.

Common situations:

• Applications. Resume, cover letter, transcripts and references in one file for a job, college or rental application.
• Government and benefits portals. Many upload forms accept only one file per field, so ID copies, pay stubs and letters have to be combined first.
• Taxes and bookkeeping. Receipts, invoices and statements for a month or a year in one document, in date order.
• School and work. A report and its appendices, created in different programs, turned in as one PDF.
• Scanned documents. Scanners and phone apps often save each page as its own PDF. Merging puts the pages back together.

You may also see this called combine PDF or join PDF. They all mean the same thing: several files become one, and the content of each page stays exactly as it was.

The tool gives you two ways to arrange your document.

Files view lists each PDF or image as one row with a thumbnail of its first page and the page count. Drag a row by its handle to move the whole file, click Sort by name to order files alphabetically (numbers are sorted naturally, so page 2 comes before page 10), rotate all pages of a file with one click, or remove a file.

Pages view shows every page as a thumbnail. Here you can move a single page from one file into the middle of another, rotate just one sideways page, or delete a blank page or an unneeded cover sheet.

Dragging works with a mouse, on a touchscreen, and from the keyboard: focus the handle, press Space to pick it up, use the arrow keys to move it, and press Space again to drop it. Screen readers announce each move.

You do not have to convert photos to PDF first. Drop JPG, PNG, WebP, GIF, BMP, AVIF or HEIC images in with your PDFs and each image becomes one page.

For image pages you can pick the page size:

Letter is the better choice when the merged PDF will be printed or sent to an office. Same size as the image keeps screenshots and scans without white borders. PDF pages are never resized; they keep their original dimensions.

Everything happens in your browser. The PDFs are read, combined and saved on your own computer or phone, and nothing is uploaded to a server. That makes the tool a reasonable choice for tax forms, medical records, contracts and other personal documents, and it also means you do not wait for uploads on a slow connection.

Merging copies the pages as they are. Text stays selectable, links and fonts are kept, and image quality does not change, because the pages are not re-rendered.

• Name files with numbers first (01-cover.pdf, 02-letter.pdf) and use Sort by name to get the order right in one click.
• Check rotated scans in the Pages view before merging; a sideways page is easy to fix here and annoying to fix later.
• Unlock protected files first. A password-protected PDF cannot be opened for merging. If you know the password, remove it with Remove PDF password, then merge.
• Too big to upload? Run the result through Compress PDF to shrink it.
• Need only part of a file? Delete the extra pages in the Pages view, or use Split PDF first.
